INSTALLATION, OPERATION AND SERVICE MANUAL

LANCASTER 4” SUBMERSIBLE PUMPS

TWO AND THREE WIRE SINGLE AND THREE PHASE ½THROUGH 7½H.P. 60Hz

CAREFULLY READ THE LITERATURE PROVIDED BEFORE INSTALLATION .

• LANCASTER PUMP recommends an experienced water-well serviceman to install new water systems or

replace an existing submersible water-well pump or pump motor. This manual should be retained for future

reference.

• INSPECT THE NEW PUMP: Occasionally, products are damaged during shipment. If the product is

damaged, contact the transportation company or your dealer. Save the products packing materials until claim is

settled. The package includes pump, motor, and motor leads (if your pump purchase includes a motor). DO NOT lift

the submersible pump by its attached electrical motor leads. 1¼” N.P.T. discharge pumps will include either a built-in

check valve or external mounted check valve with the discharge head. 2” N.P.T. discharge pumps do not include a

check valve, but a check valve is required and must be purchased separately. Three-wire, single phase pumps must

use a control box properly matched to the pumps motor. Make sure that your available voltage corresponds to that of

your motor.

• SAFETY INSTRUCTIONS:

1. WARNING - HAZARDOUS PRESSURE. Submersible pumps can develop extremely high pressure. Install a

  pressurereliefvalvecapableofpassingentirepumpowat75PSI.Donotallowpump,pressuretank,pipingor

any other system component containing water to freeze. Freezing may damage system, leading to injury or

  ooding.

2. WARNING - HAZARDOUS VOLTAGE. Voltage can shock, burn or cause death. Install, ground and wire pump

according to local and national electrical code requirements that apply. Disconnect electrical power supply before

  installingorservicingpump.Makesureelectricalpowersupplymatchesmotorelectricalrating.Aqualied

electrician is recommended.

3. Install pump according to all plumbing, pump and well code requirements.

4. Test well for purity before using well. Call your local health department for testing requirements.

5. During installation, keep well covered as much as possible to prevent leaves and foreign matter from falling into

well.

PRE-INSTALLATION PREPARATION: CAUTION: DO NOT run pump dry. Pump can be severely damaged if run dry. The pump has been factory tested with the same motor assembled to it. For safe testing, wait until pump is wired, grounded and completely submerged. THE WELL: Pump performance is based on pumping clear, cold water with no entrained air. The well driller should properly develop the well, i.e. pump out all fine sand, dirt and foreign matter, before pump is installed.

WARNING - IMPORTANT ELECTRICAL GROUNDING INFORMATION: 1. To reduce the risk of electrical shock from metal parts of the installation other than the pump, bond together all metal parts accessible at the well head (including metal discharge pipe, metal well casing, etc.). Use a metal bonding conductor at least as large as the power cable conductors running down the well to the pump’s motor. 2.

INITIAL START-UP: CHECK THE PUMP AND WELL PERFORMANCE BEFORE MAKING FINAL CONNECTION TO TANK. 1. With all electrical connections complete and pump now lowered to desired depth, install a gate valve in the discharge pipe near well for preliminary test run. Partially open the valve. 2. Turn on power to start the pump. 3. Open valve gradually to give full flow. 4. If the water is not clear, let the pump run until water clears.
